<p>
      The <b>Apache JMeter™</b> application is open source software,
      a 100% pure Java application designed
      to load test functional behavior and measure performance.  It was
      originally designed for testing Web Applications but has
      since expanded to other test functions.
    </p><h2>What can I do with it?</h2><p>
      Apache JMeter may be used to test performance both on static and dynamic
      resources, Web dynamic applications. <br>

      It can be used to simulate a heavy load on a server, group of servers,
      network or object to test its strength or to analyze overall performance
      under different load types.<br>

    </p><p>Apache JMeter features include:</p><ul>
    <li>Ability to load and performance test many different applications/server/protocol types:
        <ul>
        <li>Web - HTTP, HTTPS (Java, NodeJS, PHP, ASP.NET, …)</li>
        <li>SOAP / REST Webservices</li>
        <li>FTP</li>
        <li>Database via JDBC</li>
        <li>LDAP</li>
        <li>Message-oriented middleware (MOM) via JMS</li>
        <li>Mail - SMTP(S), POP3(S) and IMAP(S)</li>
        <li>Native commands or shell scripts</li>
        <li>TCP</li>
        <li>Java Objects</li>
        </ul>
    </li>
    <li>Full featured Test IDE that allows fast Test Plan <b>recording (from Browsers or native applications), building and debugging</b>.</li>
    <li><b><a href="usermanual/get-started.html#non_gui">CLI mode (Command-line mode (previously called Non GUI) / headless mode)</a></b> to load test from any Java compatible OS (Linux, Windows, Mac OSX, …)</li>
    <li>A complete and <b><a href="usermanual/generating-dashboard.html">ready to present dynamic HTML report</a></b></li>
    <li>Easy correlation through ability to extract data from most popular response formats, <b><a href="usermanual/component_reference.html#CSS/JQuery_Extractor">HTML</a>, <a href="usermanual/component_reference.html#JSON_Extractor">JSON </a>,
        <a href="usermanual/component_reference.html#XPath_Extractor">XML</a> or <a href="usermanual/component_reference.html#Regular_Expression_Extractor">any textual format</a></b></li>
    <li>Complete portability and <b>100% Java purity</b>.</li>
    <li>Full <b>multi-threading</b> framework allows concurrent sampling by many threads and
        simultaneous sampling of different functions by separate thread groups.</li>
    <li>Caching and offline analysis/replaying of test results.</li>
    <li><b>Highly Extensible core:</b>
      <ul>
        <li>Pluggable Samplers allow unlimited testing capabilities.</li>
        <li><b>Scriptable Samplers</b> (JSR223-compatible languages like <a href="http://groovy-lang.org">Groovy</a> and BeanShell)</li>
        <li>Several load statistics may be chosen with <b>pluggable timers</b>.</li>
        <li>Data analysis and <b>visualization plugins</b> allow great extensibility
        as well as personalization.</li>
        <li>Functions can be used to provide dynamic input to a test or provide data manipulation.</li>
        <li>Easy Continuous Integration through 3<sup>rd</sup> party Open Source libraries for Maven, Gradle and Jenkins.</li>
      </ul>

</ul><h2>JMeter is not a browser</h2><p>
JMeter is not a browser, it works at protocol level.
As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers);
however JMeter does not perform all the actions supported by browsers.
In particular, JMeter does not execute the Javascript found in HTML pages.
Nor does it render the HTML pages as a browser does
(it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
